nroff - emulate nroff command with groff
nroff [ -CchipStUv ] [ -dcs ] [ -Mdir ] [ -mname ] [ -nnum ] [ -olist ]
[ -rcn ] [ -Tname ] [ file ... ]
The nroff script emulates the nroff command using groff. Only ascii,
latin1, utf8, and cp1047 are valid arguments for the -T option, select-
ing the output encoding emitted by grotty, groff's TTY output device.
If an invalid or no -T option is given, nroff checks the current locale
to select a default output device. It first tries the locale program,
then the environment variables LC_ALL, LC_CTYPE, and LANG, and finally
the LESSCHARSET environment variable.
The -h and -c options are equivalent to grotty's options -h (using tabs
in the output) and -c (using the old output scheme instead of SGR
escape sequences). The -d, -C, -i, -M, -m, -n, -o, and -r options have
the effect described in troff(1). In addition, nroff silently ignores
the options -e, -q, and -s (which are not implemented in troff).
Options -p (pic), -t (tbl), -S (safer), and -U (unsafe) are passed to
groff. -v shows the version number.
A colon separated list of directories in which to search for the
groff executable before searching in PATH. If unset, `/usr/bin'
This shell script is basically intended for use with man(1), so warn-
ings are suppressed. nroff-style character definitions (in the file
tty-char.tmac) are also loaded to emulate unrepresentable glyphs.
